摘   要：介绍了建设地下市政综合管廊的意义以及国内外综合管廊建设发展概况。对比了现浇施工和预制装配式施工工法，并举例对两种施工工法所需工期与成本进行分析，指出了预制装配式施工具有缩短工期、降低成本、节能环保等优势。此外，还介绍了用于地下综合管廊中不同形状（如圆形、矩形和异形）的预制混凝土涵管。

Abstract：The significance of constructing underground municipal utility tunnels and the development situation of the utility tunnel at home and abroad are introduced. The cast-in-situ construction method and prefabricated fabricated construction method are compared, and required construction time and cost for a project using the two construction methods are analyzed by taking an example, which points out that the prefabricated fabricated construction method has much advantages, such as shorter the construction period, lower cost, energy conservation and environmental protection, etc. In addition, different shape (round, square and deformed) precast concrete culvert pipes for the comprehensive utility tunnels are introduced.
